GAS-SAVING DEVICE FOR ENGINES.

Specification of Letters Patent.

Application filed December 14, 1914.

To (all whom it may concern Be it known that I, FRANK YnoMAN, a citizenof the United States, residing at Ormille, in the county of Butte andState of California, have invented certain new and iiscfulIITIPIOVGITIGDtS in Gas-Saving Devices for Engines; and I do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomakeand use the same.

The present invention relates to improve ments in in nal. combustionengines and it is especially designed for use in connection I, withgasolene motors of auto vehicles.

One obgoct of this invention is to pro-- videan auxiliary attachment bymeans of which heated apor may be conveyed from the radiator to theintake manifold to augment the ellicacy oil the combustion .nixture andincrease the engines efiiciency.

Another and. further object of this inventionresides in providing ameans by the utilization o1 which the engine cylinders may be more orless cooled and the spark plugs maintained in a condition free fromcarbon particles.

Another and still further object of this invention is to provide anovelly constructed -valve for controlling the supply of heated vapor tothe intake manifold.

A final object of the invention resides in providing a means located onthe steering post in convenient reach of the operator for manipulatingthe valve.

With these and other ob'ects in view mv invention consists of certainnovel details of construction, combination and arrange; ment of parts tobe more particularl .pointed out and claimed.

in the accompanying drawings: Figure 1 is a. diagran'n'natio viewillustrating the device operatively applied to a motor vehicle; Fig. 2is an enlarged transverse vertical section of theupper portion of aradiator, illustrating, the disposition of the steam outlet pipe andshowing a fragment of a flexible tube connected to saidpipe. Fig. 3 is aside elevation of the-valve housin tu es attached thereto, together witha portion of the valve stem and operating rod connected therewith,and'Fig 4 is a trans verse vertical section certain parts being shown inelevation.

Briefly stated, my invention consists of illustrating fragments of theflexible Patented Apr. 25, 1916.

a connection between the upper portion of.

the radiator and the intake manifold of the gas engine, and a valvearranged in the length of said connection for controlling the passage ofsteam through the latter to the intake manifold, together with means formanually operating the valve, as Will be readily understood. Y

Inconnection with the steering post 1 having the usual steering wheel 2,I employ a'T- shaped valve housing or casing 3 which is secured by"suitable brackets #1 to the lower extremity of the steering post 1, asclearly shown in Fig. 1 The casing ii has a later-- ally extendingintegrally formed. tubular extension or shank 5 externally threadedcontiguous to its inner end as at 6 to receive the annular couplingmember -7 connected to the inner end of the flexible tube 8. Theextension 5 is formed with ailongitudinally extending channcl 10 whoseinner end communicates with the interior of housing 3, as clearly shownin Fig. 4. De pending from. the lower extremity of the housing 3 isanother integrally formed extension 10 threaded as at 11 to receive theannular coupling member 12 of the flexible tube 13. Extendinglongitudinally through the extension 10 is a channel 14 having its innerend communicatingwith the interior of. the housing 3 for a purpose to behereinafter explained.

Rotatably mounted Within the casing or housing 3 is an annular valve 15having therein the passage 16 adapted, upon suitable rotation of thevalve 15, to establishopen end of the housing 3, as clearly shown inFig.

A valve manipulating rod 19 has its lower .end pivotally connected tothe stem 16' of 'valve 15 and its upper end provided with an operatinghandle 20. This operating rod 19 extends longitudinally of the steeringI post 1' to which it is secured byfla suitable D In this connection itis to be noted that the handle 20 ,is disposed im bracket 21'.

: mediately below the steering heel 2 so that it may be Withinconvenient -operator at all. times.

Projecting through an opening 22 in the upper portion of the radiator"23is reach of the s formed a steam outlet pipe 24: which extends into thewater jacket 25 and passes upwardly through the latter into the annularchamber formed by the externally threaded flange 2(i'surrounding thewater orifice in jacket 25. As it would be impractical to have any Waterenter pipe 24:, as the radiator is being filled, said pipe has its upperend downwardly curved as at 26. The usual cap 26" is threaded on flange26 and closes the orifice in water jacket 25. That portion of the outletpipe projecting from the rear of the radiator is suitably connected tothe free end of flexible tube 13 so that the steam rising from the waterin the radiator may be conveyed 'from the latter through pipe 2'2, andthence through the flexible tube 13 to the valve housing 3 from whenceit may pass in a manner hereinafter to be described, to the intakemanifold "27 of the gas engine 28.

Formed in the intake manifold 28 immediately above the carbureterconnection is an annular opening 29 into which projects a short pipe 30.To the free end of pipe 30 is connected the free end of the flexibletube 8. By this structure it will become obvious that when valve.15 hasbeen rotated to establish connection between the channels 10 and 14formed in the extensions 5 and 10 of the housing 3, the steam taken fromwater tank may be conveyed to the intake manifold from whence it may bepassed to the various engine cylinders as will be read ily understoodwithout further description.

From the foregoing description it will be seen that Whenever desirable,the steam rising from the radiator may be taken from the latter andconveyed to the intake inanifold of the engine so that any globules ofliquid fuel in the mixture in the manifold may be broken up andvaporized by the steam, which consequently greatly increases theeifectlveness of the mixture and hence reduces fuel consumption. It willalso be apparent that when steam is drawn into the cylinder it willremove carbon particles from the spark plug projecting therein. By anattachment which may be readily connected that l have described certainfeatures which may be best adapted to perform the functions allotted tothem, nevertheless, I do'not wish to be limited to details other thanspecified in the appended claim.

I claim: i

In a device of the character described, the combination with a radiator,a steering post, an intake manifold of a gasolene engine, of a T-shapedvalve casing-having its head positioned parallel to the lower portion ofsaid steering post, a pair of brackets on the said lower portion of thesteering post and a third bracket adjacent its upper end, a rotatablecylindrical valve centrally arranged in the head of said casing, a stemon said valve extending through the upper end of the casing, means tosecure said valve in the casing, a rotatable operating rod having anoperating lever on its upper end, positioned parallel with the steeringpost and connected with the valve stem at its lower end, a flexibletubular connection between the upper portion of said radiator, and thelower end of the head of the casing, and a second flexible tubularconnection between the end of the shank of said T-shaped casing and theintake manifold.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

FRANK YEOMAN.
